ECHA Has Published the New Version of the Guidance on the Application of CLP Criteria

On November 13, 2024, ECHA published the new version of Guidance on the Application of the Classification, Labelling and Packaging of substances and mixtures (CLP) Criteria on its official website. This guidance aims to advance the protection of human health and the environment and to enhance chemical safety.

On November 21, 2024, a webinar was held by ECHA, during which the new CLP hazard classifications and transitional periods were discussed, including information about ED HH, ED ENV, PBT/vPvB, and PMT/vPvM.

New Hazard Classifications Under CLP

The new hazard classifications under CLP are as follows:

New criteria for endocrine disruptors (ED) have been introduced, divided into two categories: ED for human health (ED HH) and ED for the environment (ED ENV). Subcategories include EDs Cat 1 (known/presumed) and Cat 2 (suspected).
There are no subcategories for Persistent, Bioaccumulative, and Toxic (PBT),or very Persistent, very Bioaccumulative (vPvB).
Similarly, no subcategories exist for Persistent, Mobile, and Toxic (PMT), or very Persistent, very Mobile (vPvM).

The new hazard statements are presented in the following table:

Hazard Class and Category Code	Hazard Statement Code	Hazard Statement
ED HH 1	EUH380	May cause endocrine disruption in humans
ED HH 2	EUH381	Suspected of causing endocrine disruption in humans
ED ENV 1	EUH430	May cause endocrine disruption in the environment
ED ENV 2	EUH431	Suspected of causing endocrine disruption in the environment
PBT	EUH440	Accumulates in living organisms including in humans
vPvB	EUH441	Strongly accumulates in living organisms including in humans
PMT	EUH450	Can cause long-lasting and diffuse contamination of water resources
vPvM	EUH451	Can cause very long-lasting and diffuse contamination of water resources

It should be noted that there are currently no pictograms available for these hazard classes. ECHA has stated that further updates will be made in the future.

Transitional Periods

The transitional periods for substances and mixtures covered by new hazard and labelling decisions are specified by ECHA as follows:

CLP new hazard classes transitional periods

What Should Companies Do?

Companies are advised to plan their workflows while considering the transitional periods and start classifying their relevant substances and mixtures. Using the newly published guidance by ECHA will be beneficial in this regard.

Those seeking more detailed information can participate in workshops to be organized by ECHA in 2025 or review the new version of the Guidance on the Application of CLP Criteria.
